Reviews

"Based on an August 2000 symposium that highlighted EPA research, this collection overviews progress made in understanding the movement of chemicals in soil and water, monitoring environmental impacts, and developing remediation methods. The 27 papers explore chemical fate and transport models, the use of molecular biology methods for measuring ecological indicators, and groundwater and soil remediation using electrical fields. Other topics include atmospheric sources of trace metals, speciation and chemical reactions of phosphonate chelating agents in aqueous media, analysis of sediment PAH contamination, and the mechanisms controlling chlorocarbon reduction at iron surfaces."--SciTech Book News
